v STAND HAVING SUPPORTS IN ECHELON Filed March 16, 1960 2 Sheets-Sheet 2 nited States Patent 3,043,439 Patented July 10, 1962 ffice The invention relates to a stand having supports in echelon, manufactured of welded metal wires, in particular a carriage on which such a stand is mounted..

According to the invention the supports are retained between two oblique posts consisting of two metal rods having traverses, each support having near its rear edge and at each side a stub hook extending beyond one side and at a distance in front of this stub and correspond: ing to the diameter of the rods of the posts, a short roc. fixed to the frame of the support and adapted to bear against the front rod of the inclined post, when the stub engages between the two rods of the'post. The inclined posts preferably bear on a lorry, each by two vertical columns of different heights, formed of two spaced parallel rods, bent at their top in the shape of a hair-pin, the protruding bend being adapted for engaging between two transverse rods provided at the sides of the rods of the post, these rods bearing against the sides of the columns.

Embodiments of the invention are shown in the drawing.

FIG. l is a side view of a travelling stand according to the invention;

FIG. 2 is a front View of same;

FIG. 3 is a partial view in perspective, showing the connection of a support to a post with an embodiment slightly differing from that according to FIG. 1;

FIGS. 4 and 5 show details of the interconnected wires;

FIG. 6 shows the connection of a post on a column on larger scale.

The travelling stand consists of two parts, on the one hand the elements of the stand proper, formed of supports A connected between two parallel posts B and on the other hand a carriage C having columns serving as holding means for the two posts.

Each support or tray (FIGS. l, 2 and 3) is constructed of welded wire (see FIG. 3).

It has an upper bordering frame 1; at each side of this frame and at the inner side the two legs 2, 3 of a square bent wire are welded to the short side; a wire 4 parallel to the sides of the frame and situated at a lower level,

ksurrounds the front part of the support or tray between the rear legs 3 of the square bent wire; the bottom of the support or tray is formed by bent wires, a vertical leg 5 of the support being welded at the front to two parallel wires 1 and 4, and a rearwardly extending leg 6 bearing on the rear side of the frame 1 and on an intermediate transverse rod 7.

The transverse rod 7 extends beyond the short sides of the frame 1 and forms with each of its extremities a stub 8 which at its end 9 is preferably fbent in the shape of a hook.

Spaced from a stub 9 on the lower leg 2 of the wire, laterally bent in shape of a hook, connected to the short side of the frame 1 is a bar 10 making a sharp angle with the short side of the frame.

The posts B which bear the supports A between them, are symmetrical and consist of welded wires; these posts are preferably curved, in order that the supports in echelon will not interfere with each other.

They consist of two parallel rods of thick wire 11 mutually connected by small transverse bars 12 at the different levels of connection of the supports.

Each support A which is placed between the two posts B bears on a cross-bar 12 of the posts by means of its stubs 8, the bar 10 bearing against the front rod of the posts (FIG. 5). The posts B may be reinforced by two external parallel rods 13 which follow the curvature of the rods of the post and are welded to the transverse bars 12 (FIGS. 3 and 5).

The carriage C is of an arbitrary type, such as the carriage having four independent wheels shown in the drawing. This carriage bears the vertical supports of the posts. If the stand has to be placed at a fixed site, the posts may be fastened to a sock bearing on the ground. At each side and in planes corresponding to the distance between the posts, the vertical supports comprise two unequal columns D and D', each consisting of two spaced parallel rods 14. At the upper end of these wires and against the external face the legs 15 of the wire are welded which are bent in the shape of a hair-pin, so that the resulting bend 16 extends forwardly from the column. The posts in corresponding positions carry transverse rods 17 at a distance from each other equal to the width which is required for inserting the hair-pin 16 (FIG. 6), so that the posts can engage them and will bear against the foremost vertical rod I4 of the column.

The extreme simplicity of the construction of the stand appears from the preceding description. It is light and stable and can be readily mounted. Each support A, when its stubs 8 bear on the equally high transverse rods 12, takes a predetermined position, to which end its bar 10 by the own weightof the support or its load bear against the post. Such a carriage is a contrivance which can be easily handled. It is evident that the supports can be replaced by trays of sheet-metal having the same connecting elements.

I claim:

l. Display apparatus comprising, a pair of inclined curved side posts, the concave curved side of said posts facing toward the front of said display apparatus; each side post comprising a pair of rods each forming an arc and joined by transverse connecting fbars; a plurality of tray means extending between said side posts; means including a laterally projecting stub hook hooking over a transverse bar for supporting one point of each end of said tray means from said side posts; and means attached to said tray means bearing against the concave curved side of at least one of said side posts to maintain said tray means at a predetermined angle with respect to said side posts.

2. Display apparatus comprising, a pair of inclined curved side posts, the concave curved side of said posts facing toward the front of said display apparatus; each side post comprising a pair of rods each for-ming an are and joined by transverse connecting bars; a plurality `of tnay means extending between said side posts; means including a laterally projecting stub hook hooking over a transverse bar for supporting one point of each end of said tray means from said side posts; means attached to said tray means bearing against the concave curved side of at least one of said side posts to maintain said tray means at a predetermined angle with respect to said side poss; and traveling carriage means supporting said side pos s.
